| Abstract: | Based on the international advanced measurement principle of monitoring system using distributed fiber optic strain sensor, a model based on neural network with 4 layers is established in allusion to strain change of particular location, which can be used to forecast ＇the structural deformation on particular location. This prediction method has been validated by the test data, and the satisfying results show that it has a certain practical value. |
